Description: This function changes the UV line density of the selected surfaces.
Usage:
1. DSI prompts the user to select a surface on the screen.
2. DSI labels the edge numbers on the surface and prompts the user to enter the number of UV lines along edges 1 and 2.
3. DSI creates a set of UV lines along edges 1 and 2. These UV lines are included in the original part.
Note: This operation changes only the appearance of the selected surfaces. It does not change the integrity of the surface.
